This analysis illustrates a time series analysis of the evolution of satellite-detected surface waters and potentially affected villages in Sanamxay district, Attapeu province, based on satellite data recorded on 13, 25 and 29 July 2018.

This map illustrates a time series analysis of the evolution of satellite-detected surface waters in Sanamxay district, Attapeu province, based on satellite data collected on 13, 25 and 29 July 2018. Within the current map extent, on 13 July 2018, before the collapse of the dam, a total surface of 47,717 ha was detected as inundated and the reservoir controlled by the dam was full of water. As of 25 July 2018, two days after the dam collapsed, an additional surface of 7,531 ha of inundated areas were detected, representing an increase of the surface waters of 16%.

Situation overview & potential additonal flooded areas after the collapse of the Xe-Namoy dam, river overflow and heavy rain. The derived product illustrates the evolution of the event upstream and downstream Vang Ngao and Xe Kong rivers. Close-up view insets using Sentinel-1 imagery collected on the 13 and 25 July shows comparison between these dates. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR - UNOSAT.

Thanks to the European Union’s Copernicus programme, vast quantities of satellite data are freely available to manage the environment and benefit European citizens. While this offers a wealth of opportunities, downloading and storing these data involves some complex logistical challenges – but this is about to change.

With such a lot of data available, the European Commission is making efforts to make sure that the process of accessing these data and information is easier so that issues associated with downloading and storing can be avoided.

The recent low pressure system in Indian Ocean caused heavy rainfall across Sri Lanka since 14 May 2016 causing widespread flooding and landslide in as many as 19 districts, including around Colombo. Kelani Ganga is one of the main river basin in Sri Lanka which is currently experiencing large scale flooding and subsequent damage to property and livelihoods. Kelani basin received 350 mm of total rainfall within three days (15 to 17 May 2016).

Situation report on severe floods caused by heavy rainfall in coastal Andhra Pradesh (India) were analyzed using Sentinel-1 satellite images obtained from European Space Agency. From the observation it is very clear large agriculture areas and rural populations in Nellore and Chittoor were severely affected due to floods.

At least 165 people have lost their lives as heavy rains resulted in floods in Tamil Nadu. Chennai has been badly affected by floods as around 59 people have been killed in the capital so far.
